I am. I think. I will.

At the beginning of chapter 11, Equality says "I am. I think. I will."
At this point in the novel, Equality has fully realized that the foundation of man's emotions was based on individualistic terms. After he read the texts found in the house, he realized that society was vastly different from the dystopian society he had lived in. Previous societies had emphasized the achievements of the individual, rather than the group. When he read this, he shed tears, not for himself, but for the current condition of humanity. He realized that these "transgressions" and "Sins" he had committed were all natural. In fact, they were apart of human nature. That is why, he thought, he didn't feel any remorse or guilt for the "sins" he had committed.
The basis of this quote is formed on forbidden thinking in the society. Everyone in society learned to refer to themselves as "we" rather than I. This emphasized the common good for the community rather than individualism. However, once Equality learned the existence of the word "I", he fully embraced the lifestyle and thinking of "I"
